Any other Linux users love their android phones a little bit more knowing that it is part of the open source movement? It will be cool to see what people can do while tinkering with these "super phones". The Compiz effects on a desktop are awesome, but could be even cooler with the touch interface of a phone (custom of course). I am imaging different effects for programs closing or simply returning them to the background. Slick transitions while dragging or moving to a new desktop. Live wallpaper is cool on 2.1, but I think that people would enjoy a layer of 2d or 3d effects over their own background pictures. An example being a picture of someone standing outside in the snow, while digital snow is falling and blowing over the picture (but under the icons/widgets). The same can be used for a picture of a fall day, with your favorite lady smiling at you, while leaves are falling slowly.
